A Home Patented Sept. 8, 1942 UNITED STATES PATENT OFFICE STORM DOOR PROTECTING AND CLOSING MECHANISM 2 Claims.

This invention appertains to new and useful improvements in attachment for storm doors to prevent the same from blowing open in windy weather and damaging the fastening means thereof.

Another important object of the invention is to provide protecting means for storm doors which will only permit the door to be opened a certain amount suflicient for passage of a person and which will automatically close the door upon being released by the person opening the same.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary perspective view showing the mechanism with the associated storm door in open position.

Figure 2 is a horizontal sectional view showing the mechanism associated with a storm door.

Figure 3 is a fragmentary vertical sectional view through a doorway showing the storm door in closed position and in association with the closing mechanism.

Figure 4 is a fragmentary longitudinal sectional view through the closing mechanism.

Figure 5 is a fragmentary sectional view showing the mechanism in plan View.

Figure 6 is a horizontal sectional view showing a slightly modified arrangement of the closing means.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a door frame in which is mounted an ordinary door 6 and a storm door 1. Numeral 8 generally refers to the protecting and closing mechanism for the storm door I.

This mechanism 8 consists of an elongated barrel 9 externally threaded at its lower end for disposition into an internally threaded cap I D. The upper end of the barrel 9 is externally threaded for disposition into one end of an elbow II, the other end of the elbow H receiving the threaded end of a tubular guide l2.

Loop defining brackets l3, M are secured to one side member of the door frame 5 after the barrel 9 has been properly positioned, the bracket l3 adjacent the elbow ll while the bracket I4 is located adjacent the cap l0. There is sufficient play between the barrel 9 and the brackets l3 and M to permit rotation of the barrel 9.

A headed member 15 extends through the bottom of the cap l0 and has an eye l6 at its inner end, and to this eye It connects the lower end of the tension spring ll. A flexible line 18 connects to the other end of the spring I! and extends upwardly, through the elbow II and through the tubular guide I2. The upper end of this line I8 terminates in an eye [9 through which extends a chain 20. This chain 20 extends from an eye or hook 2| on the upper portion of the frame 5 to an eye or hook 22 located on the storm door 1.

It can now be seen that when the storm door 1 is opened and the chain 20 straightened out as shown in Figure 1, a pull is exerted by the flexible line l8 on the spring ll. As soon as the door I is released, the spring I! will pull the line l8 into the barrel 9 and, of course, cause lapping of the chain 20 as shown in Figure 2, causing the storm door I to close.

As shown in Figure 6, reference character 5a denotes a door frame while reference characters 6a and 1a denote the usual door and storm door, respectively. The present invention is generally referred to by reference character 8a and the only difference is that the chain 20a extends from anchoring points on the doors 6a, la instead of from the frame 5a to the door 1a. In other words, after a person has opened the ordinary door 6a, he then opens the storm door 1a and as he goes outdoors the ordinary door 6a will automatically close without he or she taking the hands off of the storm door la.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In combination, a door frame, an ordinary door, a storm door, a flexible line connection between the doors, a vertically disposed barrel having a tension spring therein, and a second flexible line extending from the spring out of the barrel and to the intermediate portion of the first-mentioned flexible line.

2. A closure for doors comprising a tube having a longitudinally disposed tension spring therein anchored at its lower end to the lower end portion of the tube, a flexible line extending from the upper end of the spring and through the upper end of the tube, and attached to a door, said barrel being rotatably mounted on the frame for swinging in accordance with the opening and closing movement of the door.
